Which segment is sent by the client to synchronize sequence numbers during the three-way handshaking process?ACK segmentSYN + ACK segmentFIN segmentSYN segment

TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload.  The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500.  Suppose that the segment with sequence number 300 is lost.  The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received). Complete the sentences below ....After receiving segment 100, the receiver responds with an ACK with value: After receiving segment 200, the receiver responds with an ACK with value: After receiving segment 500, the receiver responds with an ACK with value: After receiving the retransmitted segment 300, the receiver responds with an ACK with value:

The sequence of SYN, SYN/ACK, and ACK packets is known as the three-way handshake high five two-way handshake four-way handshake

c) In a TCP connection, the initial sequence number at the client site is 2717. The client opens the connection, sends three segments, the second of which carries 1000 bytes of data, and closes the connection. What is the value of the sequence number in each of the following segments sent by the client? [2 Marks] i) The SYN segment ii) The data segment iii) The FIN segment

The figure below shows the timing diagram for a TCP connection between Hosts A and B from the beginning to the end. First, we see the 3-way handshake. The client (Host A) combines 50 bytes of data with the last ACK of the 3-way handshake. The server (Host B) combines 100 bytes of data with the ACK packet sent back to the client. The client (Host A) closes the connection at this point which results in a FIN segment being sent to the server (Host B), which is combined with the ACK for the 100-byte data. After a little while, the server (Host B) closes the connection as well.Enter the numeric values for a, b, c, d, e and f in the spaces provided below. No explanation is necessary. 0.5 mark for each.

Consider the figure below, where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8. Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown.The segment sent at t=4 is lost, as is the ACK segment sent at t=7.What is the sequence number of the segment sent at t=2? What is the ACK value carried in the receiver-to-sender ACK sent at t = 6? What is the ACK value carried in the receiver-to-sender ACK sent at t = 8? What is the ACK value carried in the receiver-to-sender ACK sent at t = 10?
